Backgrounds Moral distress significantly affects pediatric ICU nurses, leading to nurse burnout, increased turnover and reducing patient care quality. Despite its importance, there’s a notable gap in knowledge on how to manage it effectively. Aims This review aimed to systematically identify and analyze coping strategies and interventions targeting moral distress among pediatric nurses in ICU, uncovering research gap and future studies directions. Methods A scoping review was conducted followed framework by Levac, Colquhoun, and O'Brien and Arksey and O'Malley. Searches were (...) performed in 11 electrical databases, like PubMed and China Biology Medicine disc, within a timeframe of the database construction to November 2023, and performed literature screening and data extraction. Results Sixteen articles were ultimately included. Coping strategies adopted by pediatric ICUs nurses can be categorized into adaptive and maladaptive strategies, with the latter including passive acceptance, taking leave, and drinking, while the former involve pursuing interests outside of work, reflection and philosophizing, and communication. Nine articles described and evaluated the effectiveness of interventions for moral distress, categorizing them into individual and institutional levels. Individual-level interventions include Interprofessional Perspective-Taking, the PICU Resiliency Bundle, Ethics Education/Skills, and the Center for Caring. Institutional-level interventions encompasses Comprehensive Care Round, Goals of Care Conversations, Pediatric Ethics and Communication Excellence Rounds, Nursing Ethics Council, and Medical Ethical Decision-Making, though not all were effective in alleviating moral distress. Conclusions Nurses often use self-adjustment strategies for moral distress, institutional ethical support focusing on enhancing nurses’ moral resilience, promoting reflective thinking and improving communication remains crucial. Various interventions for moral distress are currently available, but nurse engagement is low and their effectiveness remained to be verified. Future studies should explore what aids or hinders these interventions. There’s also a need for large, multicenter trials and ongoing evaluations to create effective support systems for pediatric ICU nurses. (shrink)

If there are fundamental laws of nature, can they fail to be exact? In this paper, I consider the possibility that some fundamental laws are vague. I call this phenomenon 'fundamental nomic vagueness.' I characterize fundamental nomic vagueness as the existence of borderline lawful worlds and the presence of several other accompanying features. Under certain assumptions, such vagueness prevents the fundamental physical theory from being completely expressible in the mathematical language. Moreover, I suggest that such vagueness can be regarded as (...) 'vagueness in the world.' For a case study, we turn to the Past Hypothesis, a postulate that (partially) explains the direction of time in our world. We have reasons to take it seriously as a candidate fundamental law of nature. Yet it is vague: it admits borderline (nomologically) possible worlds. An exact version would lead to an untraceable arbitrariness absent in any other fundamental laws. However, the dilemma between fundamental nomic vagueness and untraceable arbitrariness is dissolved in a new quantum theory of time's arrow. (shrink)

If the Past Hypothesis underlies the arrows of time, what is the status of the Past Hypothesis? In this paper, I examine the role of the Past Hypothesis in the Boltzmannian account and defend the view that the Past Hypothesis is a candidate fundamental law of nature. Such a view is known to be compatible with Humeanism about laws, but as I argue it is also supported by a minimal non-Humean "governing'' view. Some worries arise from the non-dynamical and time-dependent (...) character of the Past Hypothesis as a boundary condition, the intrinsic vagueness in its specification, and the nature of the initial probability distribution. I show that these worries do not have much force, and in any case they become less relevant in a new quantum framework for analyzing time's arrows---the Wentaculus. Hence, the view that the Past Hypothesis is a candidate fundamental law should be more widely accepted than it is now. (shrink)

Two of the most difficult problems in the foundations of physics are (1) what gives rise to the arrow of time and (2) what the ontology of quantum mechanics is. I propose a unified 'Humean' solution to the two problems. Humeanism allows us to incorporate the Past Hypothesis and the Statistical Postulate into the best system, which we then use to simplify the quantum state of the universe. This enables us to confer the nomological status to the quantum state in (...) a way that adds no significant complexity to the best system and solves the ''supervenient-kind problem'' facing the original version of the Past Hypothesis. We call the resultant theory the Humean unification. It provides a unified explanation of time asymmetry and quantum entanglement. On this theory, what gives rise to time's arrow is also responsible for quantum phenomena. The new theory has a separable mosaic, a best system that is simple and non-vague, less tension between quantum mechanics and special relativity, and a higher degree of theoretical and dynamical unity. The Humean unification leads to new insights that can be useful to Humeans and non-Humeans alike. (shrink)

In this short survey article, I discuss Bell’s theorem and some strategies that attempt to avoid the conclusion of non-locality. I focus on two that intersect with the philosophy of probability: (1) quantum probabilities and (2) superdeterminism. The issues they raised not only apply to a wide class of no-go theorems about quantum mechanics but are also of general philosophical interest.

If an asymmetry in time does not arise from the fundamental dynamical laws of physics, it may be found in special boundary conditions. The argument normally goes that since thermodynamic entropy in the past is lower than in the future according to the Second Law of Thermodynamics, then tracing this back to the time around the Big Bang means the universe must have started off in a state of very low thermodynamic entropy: the Thermodynamic Past Hypothesis. In this paper, we (...) consider another boundary condition that plays a similar role, but for the decoherent arrow of time, i.e. the subsystems of the universe are more mixed in the future than in the past. According to what we call the Entanglement Past Hypothesis, the initial quantum state of the universe had very low entanglement entropy. We clarify the content of the Entanglement Past Hypothesis, compare it with the Thermodynamic Past Hypothesis, and identify some challenges and open questions for future research. (shrink)

Behaving ethically depends on the ability to recognize that ethical issues exist, to see from an ethical point of view. This ability to see and respond ethically may be related more to attributes of corporate culture than to attributes of individual employees. Efforts to increase ethical standards and decrease pressure to behave unethically should therefore concentrate on the organization and its culture. The purpose of this paper is to discuss how total quality (TQ) techniques can facilitate the development of a (...) cooperative corporate culture that promotes and encourages ethical behavior throughout an organization.

Drawing on the results of modem psychology and cognitive science we suggest that the traditional theory of concepts is no longer tenable, and that the alternative account proposed by Kuhn may now be seen to have independent empirical support quite apart from its success as part of an account of scientific change. We suggest that these mechanisms can also be understood as special cases of general cognitive structures revealed by cognitive science. Against this background, incommensurability is not an insurmountable obstacle (...) to accepting Kuhn's position, as many philosophers of science still believe. Rather it becomes a natural consequence of cognitive structures that appear in all human beings. (shrink)

What exists at the fundamental level of reality? On the standard picture, the fundamental reality contains (among other things) fundamental matter, such as particles, fields, or even the quantum state. Non-fundamental facts are explained by facts about fundamental matter, at least in part. In this paper, I introduce a non-standard picture called the "cosmic void” in which the universe is devoid of any fundamental material ontology. Facts about tables and chairs are recovered from a special kind of laws that satisfy (...) strong determinism. All non-fundamental facts are completely explained by nomic facts. I discuss a concrete example of this picture in a strongly deterministic version of the many-worlds theory of quantum mechanics. I discuss some philosophical and scientific challenges to this view, as well as some connections to ontological nihilism. (shrink)

To correct the misconception that incommensurability implies incomparability, Kuhn lately develops a new interpretation of incommensurability. This includes a linguistic theory of scientific revolutions (the theory of kinds), a cognitive exploration of the language learning process (the analogy of bilingualism), and an epistemological discussion on the rationality of scientific development (the evolutionary epistemology). My focus in this paper is to review Kuhn's effort in eliminating relativism, highlighting both the insights and the difficulties of his new version of incommensurability . Finally (...) I suggest that some of Kuhn's difficulties can be overcome by adopting a concept of rationality that filly appreciates the important role of instruments in the development of science. (shrink)

In this paper we examine the pattern of conceptual change during scientific revolutions by using methods from cognitive psychology. We show that the changes characteristic of scientific revolutions, especially taxonomic changes, can occur in a continuous manner. Using the frame model of concept representation to capture structural relations within concepts and the direct links between concept and taxonomy, we develop an account of conceptual change in science that more adequately reflects the current understanding that episodes like the Copernican revolution are (...) not always abrupt. When concepts are represented by frames, the transformation from one taxonomy to another can be achieved in a piecemeal fashion not preconditioned by a crisis stage, and a new taxonomy can arise naturally out of the old frame instead of emerging separately from the existing conceptual system. This cognitive mechanism of continuous change demonstrates the constructive roles of anomaly and incommensurability in promoting the progress of science. (shrink)

Banks play a unique role in society. They not only maximize profits but also consider the interests of stakeholders. We investigate whether banks consider firms’ pollution records in their lending decisions. The evidence shows that banks offer significantly higher loan spreads, higher total borrowing costs, shorter loan maturities, and greater collateral to firms with higher levels of chemical pollution. The costly effects are stronger for borrowers with greater risk and weaker corporate governance. Further, the results show that banks with higher (...) social responsibility account for their borrowers’ environmental performance and charge higher loan spreads to those with poor performance. These results support the idea that banks with higher social responsibility can promote the practice of business ethics in firms. (shrink)

A decade ago, the “new sociology of masculinity” emerged as an exciting new paradigm for understanding gender, emphasizing the study of “hegemonic power relations” among men and women. However, subsequent research has not fully redeemed the promise of the NSM, failing to seriously engage the theoretical implications of studying hegemony. This article addresses the lacunae by presenting a theoretically informed analysis of life history interviews with Chinese American men. Its chief empirical question is how Chinese American men “achieve” masculinity in (...) the face of negative stereotypes. This is accomplished, it is found, through four possible gender strategies: compensation, deflection, denial, or repudiation. The author then fashions a theoretical account of these strategies to show how they can reproduce the social order by striking a hegemonic bargain, which occurs when a Chinese American man's gender strategy involves consciously trading on—or unconsciously taking advantage of—the “privileges” of his race, gender, class, generation, and/or sexuality for the purposes of elevating his masculinity.

The current public health crisis has exposed deep cracks in social equality and justice for marginalised and vulnerable communities around the world. The reported rise in the number of ‘do not resuscitate’ orders being imposed on people with disabilities has caused particular concerns from a human rights perspective. While the evidence of this is contested, this article will consider the human rights implications at stake and the dangers associated with using ‘quality of life’ measures as determinant of care in medical (...) decision-making and triage assessments.

In this paper, we propose a method to design the pseudorandom number generator using three kinds of four-wing memristive hyperchaotic systems with different dimensions as multientropy sources. The principle of this method is to obtain pseudorandom numbers with good randomness by coupling XOR operation on the three kinds of FWMHSs with different dimensions. In order to prove its potential application in secure communication, the security of PRNG based on this scheme is analyzed from the perspective of cryptography. In addition, PRNG (...) has passed the NIST 800.22 and ENT test, which shows that PRNG has good statistical characteristics. Finally, an image encryption algorithm based on PRNG is adopted. In the encryption algorithm, the optimized Arnold matrix scrambling method and the diffusion processing based on XOR are used to obtain the final encrypted image. Through the evaluation of encryption performance, it is concluded that there is no direct relationship between the pristine image and encrypted image. The results show that the proposed image encryption scheme has good statistical output characteristics and security performance in line with cryptography. (shrink)

The Zhuangzi is perhaps the one and only work in classical Chinese philosophy that never fails to blow one's mind with its exquisite intertwining of high frivolousness, literary power, ambiguity, ambivalence, profundity and provocativeness all at once. There is urgent need of a translation able to transmit this paradoxical reading experiences as it is. Happily, all of these qualities, with the possible exception of ambiguity, are revealed in Brook Ziporyn's Zhuangzi: The Complete Writings, with both poetry and precision. Through a (...) hermeneutical approach that inter-contextualizes each line and each word of the thirty-three chapters, especially many controversial places, he makes the chaotic and unsystematic text...

Harry Frankfurt had insightfully pointed out that an agent acts freely when he acts in accord with the mental states with which he identifies. The concept of identification rightly captures the ownership condition (something being one’s really own), which plays a significant role in the issues of freedom and moral responsibility. For Frankfurt, identification consists of one’s forming second-order volitions, endorsing first-order desires, and issuing in his actions wholeheartedly. An agent not only wants to φ but also fully embraces his (...) desire to φ (and φ). Frankfurt’s official theory above encounters some serious problems, especially since it is believed that his concept of wholehearted identification is too strong to be necessary for freedom. In this paper, I propose that we can uncouple identification from wholeheartedness and thus get two different senses of identification: weak identification and strong identification. Then, I argue that this distinction does a better job than Frankfurt’s official theory. On the one hand, weak identification is enough for ownership and freedom and thus more promising than strong identification; on the other hand, this distinction has an attractive implication that it fits well with our intuition about the degree of freedom and responsibility.

We expect the laws of nature that describe the universe to be exact, but what if that isn't true? In this popular science article, I discuss the possibility that some candidate fundamental laws of nature, such as the Past Hypothesis, may be vague. This possibility is in conflict with the idea that the fundamental laws of nature can always and faithfully be described by classical mathematics. -/- [Bibliographic note: this article is featured on the magazine website under a different title (...) as "The fuzzy law that could break the idea of a mathematical universe" and on the magazine cover as "The Flaw at the Heart of Reality: Why precise mathematical laws can never fully explain the universe."

Let ℋ be a finite-dimensional complex Hilbert space and D the set of density matrices on ℋ, i.e., the positive operators with trace 1. Our goal in this note is to identify a probability measure u on D that can be regarded as the uniform distribution over D.

Widespread unethical corporate misconduct in an industry triggers industry-wide crises. This research investigates how industry misconduct affects consumers’ trust in the industry, by incorporating insights from a micro-level psychological aspect of institutions. The conceptual framework proposes that consumer legitimacy judgement lies at the core of industry trust, following an industry-wide crisis. The results demonstrate that perception of normalisation of misconduct affects industry trust through consumer legitimacy judgement. Moreover, the PNM-CLJ-industry trust relationship is stronger during industry-wide crises compared with crises that (...) involve only one firm, and this relationship is not dependent on the frequency of crises. This research contributes to the knowledge of product-harm crisis by deepening understanding of the trust erosion mechanism during industry-wide crises, with a focus on legitimacy judgement. The findings have implications for prevention of industry-wide crises and for boosting ethically desirable business activities. (shrink)

In this paper I examine a cognitive mechanism of incommensurability. Using the frame model of concept representation to capture structural relations within concepts, I reveal an ontological difference between object and event concepts: the former are spatial but the latter temporal. Experiments from cognitive sciences further demonstrate that the mind treats object and event concepts differently. Thus, incommensurability can occur in conceptual change across different ontological categories. I use a historical case to illustrate how the ontological difference between an object (...) and an event concept actually caused incommensurability in the context of nineteenth‐century optics. The cognitive and historical analyses indicate that incommensurability can be a local phenomenon and does not necessarily imply incomparability. (shrink)

Electroencephalography (EEG) is a non-invasive method to identify markers of treatment response in major depressive disorder (MDD). In this review, existing literature was assessed to determine how EEG markers change with different modalities of MDD treatments, and to synthesize the breadth of EEG markers used in conjunction with MDD treatments. PubMed and EMBASE were searched from 2000 to 2021 for studies reporting resting EEG (rEEG) and transcranial magnetic stimulation combined with EEG (TMS-EEG) measures in patients undergoing MDD treatments. The search (...) yielded 966 articles, 204 underwent full-text screening, and 51 studies were included for a narrative synthesis of findings along with confidence in the evidence. In rEEG studies, non-linear quantitative algorithms such as theta cordance and theta current density show higher predictive value than traditional linear metrics. Although less abundant, TMS-EEG measures show promise for predictive markers of brain stimulation treatment response. Future focus on TMS-EEG measures may prove fruitful, given its ability to target cortical regions of interest related to MDD. (shrink)

The present study is the first to empirically test a hierarchical, positive-oriented model of self and its relationship to the second language (L2) achievement motivation, and compare it in three different cultural contexts of Japan, U.S. and Taiwan. Based on the L2 self model (Lake, 2016), three levels of constructs were developed: Global Self (i.e., Flourishing, Curiosity, and Hope); Positive L2 domain self (i.e., interested-in-L2 self, harmonious passion for L2 learning, and mastery L2 goal orientation); and L2 Motivational Variables (i.e., (...) reading, speaking and listening self-efficacy). A total of 667 students participated in this study, including 181 first-year college students in Japan, 159 high school students in Taiwan, and 327 college students in the U.S. All the participants were learning a L2 in school. Results showed that the measures of positive global self, L2 domain self, and L2 motivational self all had a stronger relationship within their respective levels, and progressively weaker relationships as level of generality/specificity became more distal. Furthermore, the relationships among measures varied in the differing cultural contexts with the Japan-based student participants relatively lower on all measures. (shrink)

Challenge-oriented organizational citizenship behavior or the organization-improving tasks employees perform beyond their job description is important for high organizational performance, but the organizational factors influencing it are poorly understood. In this study, we explored how inclusive leadership influences employees’ challenge-oriented organizational citizenship behavior in the Chinese context, drawing on data from 558 employees in high-tech industries. Multivariate correlation analysis showed that inclusive leadership promotes employees’ challenge-oriented organizational citizenship behavior and that this influence is partly mediated by work engagement. Further, it (...) showed that organizational innovative atmosphere has a moderating effect on the relationship between inclusive leadership and employees’ challenge-oriented organizational citizenship behavior. In effect, this study expands the range of predictive variables for challenge-oriented organizational citizenship behavior and provides not only theoretical insight but also practical guidance for leaders who seek to motivate this behavior in their employees.

This paper proposes an account of natural analogy in scientific theorizing via Mary Hesse’s original understanding of analogical reasoning. Starting with discussing Hesse’s examples and her symbolic scheme, I argue that the traditional distinction between the type of formal analogy and the type of material analogy should be abandoned. All analogies in theorizing, that are both formal and material, contain a set of pretheoretic associations and a theoretic structure between two analogues. I thus provide a new interpretation of Hesse’s symbolic (...) scheme to reveal the pretheoretical and the structural dimensions of analogy and further illustrate the account of natural analogy by applying it to the history of the construction of Coulomb’s law, which is traditionally seen as a typical case of formal analogy, arguing that pretheoretic associations as well as a theoretic structure play a necessary role in this case. In the final part of this paper, I argue that the account of natural analogy is preferable to Dedre Gentner’s structural mapping theory. (shrink)

Mencius, who often spoke of ming in different senses among which only one can be taken as fate, upheld two doctrines of fate--moral determinism and blind, unalterable fate--but he was prone to apply the former to collective entities, and the latter to individual persons. This bi-level distinction, which is at variance with the non-distinction in both Moism and Taoism, exercised a profound influence upon the minds of later Confucians.

I propose a new perspective on the study of scientific revolutions. This is a transformation from an object-only perspective to an ontological perspective that properly treats objects and processes as distinct kinds. I begin my analysis by identifying an object bias in the study of scientific revolutions, where it takes the form of representing scientific revolutions as changes in classification of physical objects. I further explore the origins of this object bias. Findings from developmental psychology indicate that children cannot distinguish (...) processes from objects until the age of 7, but they have already developed a core system of object knowledge as early as 4 months of age. The persistence of this core system is responsible for the object bias among mature adults, i.e., the tendency to apply knowledge of physical objects to temporal processes. In light of the distinction between physical objects and temporal processes, I redraw the picture of the Copernican revolution. Rather than seeing it as a taxonomic shift from a geocentric to a heliocentric cosmology, we should understand it as a transformation from a conceptual system that was built around an object concept to one that was built around a process concept.

ABSTRACT The ongoing Sino-U.S. trade dispute between the world’s two largest economies has since 2018 attracted much attention from the international media. This study used the approach of corpus-assisted discourse studies to compare how leading English-language newspapers from each side—The New York Times and China Daily — discursively constructed this issue. The findings indicated that while NYT tended to profile the trade conflict as a ‘war’ in line with mainstream hard-line ideologies that emphasize China’s presumed threat to national security of (...) the U.S., CD sought to dial down the rhetoric and showed a preference for defining the matter as a ‘friction’, consistent with the tenet of ‘pragmatic nationalism’ endorsed by the Communist Party of China. Accordingly, the two newspapers framed the causes, moral evaluation/consequences, and treatment of the issue in congruence with their respective dominant metaphors by means of various linguistic patterns. These differences are interpreted with regard to each side’s underlying ideologies and national interests. (shrink)

Over the past generation, the rise of East Asia and especially China, has brought about a sea change in the economic and political world order. At the same time, global warming, environmental degradation, food and water shortages, population explosion, and income inequities have created a perfect storm that threatens the very survival of humanity. It is clear now that the Westphalian model of individual sovereign states seeking their own self-interest will not be able to respond effectively to this win-win or (...) lose-lose crisis. In this volume, a cadre of distinguished scholars comes together to reflect on Confucianism and Deweyan pragmatism as possible resources for a new geopolitics that begins from an ontology of interdependence and recognizes the irreducibly ecological nature of the human experience at every level. Both Confucian and Deweyan traditions emphasize the primacy of experience, the importance of vital relationality, and the moral roots of good governance. The potential benefits of conceptually blending the two are many. Indeed, the contemporary Chinese philosopher Tang Junyi provides us with a cosmological understanding of the "idea" of Confucianism that, in parallel to Dewey's "idea" of democracy, can enable us to anticipate the core values, if not the specific contours, of a "Confucian democracy." Just as Dewey's "idea" of democracy is his vision of the flourishing communal life made possible by the contributions of the uniquely distinguished persons that constitute it, Tang Junyi's Confucianism is a pragmatic naturalism directed at achieving the most highly integrated cultural, moral, and spiritual growth for the individual-in-community. In both, we find an affirmation of communal harmony as a process "starting here and going there" through which those involved learn together to do ordinary things in extraordinary ways. Just such a cosmological understanding of democracy is one way of describing what will be needed to address the many predicaments characterizing the environmental, cultural, socioeconomic, and political dynamics of the twenty-first century.

: This paper offers a preliminary analysis of conceptual change between event concepts. It begins with a brief review of the major findings of cognitive studies on event knowledge. The script model proposed by Schank and Abelson was the first attempt to represent event knowledge. Subsequent cognitive studies indicated that event knowledge is organized in the form of dimensional organizations in which temporally successive actions are related causally. This paper proposes a frame representation to capture and outline the internal structure (...) of event concepts, in particular, their causal connections. The frame representation offers an effective method to analyze the relations between event concepts, and to expose the unique cognitive mechanisms behind conceptual change involved event concepts. Finally this paper shows that the frame representation of event concepts is instrumental to understanding an important historical episode of conceptual change in the context of nineteenth-century optics.

Recent studies of the rubber hand illusion (RHI) have shown that the sense of body ownership is constrained by several factors and yet is still very flexible. However, exactly how flexible is our sense of body ownership? In this study, we address this issue by investigating the following question: is it possible that one may have the illusory experience of owning four hands? Under visual manipulation, the participant adopted the experimenter’s first-person perspective (1PP) as if it was his/her own. Sitting (...) face to face, the participant saw four hands—the experimenter’s two hands from the adopted 1PP together with the subject’s own two hands from the adopted third-person perspective (3PP). We found that: (1) the four-hand illusion did not occur in the passive four-hand condition. (2) In the active four-hand condition, the participants tapped their index fingers, imitated by the experimenter. When tactile stimulations were not provided, the key illusion was not induced, either. (3) Strikingly, once all four hands began to act with the same pattern and received synchronous tactile stimulations at the same time, many participants felt as if they had two more hands. These results show that the sense of body ownership is much more flexible than most researchers have suggested. (shrink)

In The Humanist Spirit of Daoism, Chen Guying presents a concise overview of his understanding of the meaning and significance of Daoist philosophy. Chen is a leading contemporary Chinese thinker and spokesperson for a new Daoist approach to existential and socio-political issues. He was born in mainland China in 1935, but after having resettled to Taiwan, he received his education there and was a student activist in the 1960s. He became famous in the Chinese-speaking world with his writings (...) on Nietzsche, Laozi and Zhuangzi. At present he is a Professor at Peking University. This volume collects representative essays from the past 25 years which not only outline Chen's interpretation of Daoism as a deeply humanist way of thinking and living, but also show how he employs this philosophy in a critique of totalitarianism and neo-imperialism.

It is often thought that epistemic relations between experience and belief make it possible for our beliefs to be about or "directed towards" the empirical world. I focus on an influential attempt by John McDowell to defend a view along these lines. According to McDowell, unless experiences are the sorts of things that can be our reasons for holding beliefs, our beliefs would not be "answerable" to the facts they purportedly represent, and so would lack all empirical content. I argue (...) that there is no intelligible conception of what it is for beliefs to be answerable to the facts that supports McDowell's claim that our empirical beliefs must be justified by experience.

In the past decades, considerable attention has been paid to the chaos-based image encryption schemes owing to their characteristics such as extreme sensitivity to initial conditions and parameters, pseudo-randomness, and unpredictability. However, some schemes have been proven to be insecure due to using a single chaotic system. To increase the security, this work proposes a novel image encryption scheme based on the piecewise linear chaotic map and the standard map. To the best of our knowledge, it is the first chaos-based (...) image encryption scheme combining the PWLCM with the standard map, which adopts permutation-diffusion structure. Unlike the traditional scrambling way, a hierarchical diffusion strategy, which not only changes the pixel position but also modifies the value, is employed in the permutation phase. The operation model of row-by-row and column-by-column is further used to enhance the efficiency in the diffusion process. Consequently, a good trade-off efficiency and security can be achieved. Furthermore, the numerical simulations and performance analyses illustrate that the proposed encryption scheme can be used in practical application scenarios requiring lightweight security. (shrink)

In the years 2009 to 2016, approximately 35% of Standard & Poor’s (S&P) 500 firms had at least one director with a professional background in private, not-for-profit organizations (NGO director). Yet research provides little guidance on what kind of firms are more likely to have NGO directors on their boards, neither do we know these directors’ effects on firm strategic outcomes. Our study examines the above two questions in the context of corporate social responsibility (CSR), taking the lens of resource (...) dependence theory. Results from an analysis of all firms included in the S&P 500 index between 2010 and 2016 show that the number of NGO directors serving on a firm’s board in a certain year is positively related to the extent to which the firm displays poor CSR performance in the prior year. We also find that NGO directors on boards are not associated with immediate improvements in CSR performance; rather, their positive influence on CSR performance takes hold after 3 years. Our findings suggest that whereas NGO directors may potentially be appointed to a firm’s board for legitimization reasons, these directors are associated with enhanced CSR performance in the long term.
